Chapter 7: Introduction to Ad Hoc Wireless Networks

1. Definition

• An ad hoc wireless network consists of mobile nodes (hosts) connected by wireless links.
• The network topology (physical connectivity) changes randomly due to node mobility.

2. Challenges

• Traditional wired network routing protocols cannot be used due to:
  • Dynamic topology
  • Lack of centralized infrastructure (e.g., base stations or access points)
  • Bandwidth constraints
  • Resource (energy) constraints

3. Content Overview

• Issues in designing a routing protocol for ad hoc wireless networks
• Classifications of routing protocols
• Discussion of existing routing protocols with illustrations

Issues in Designing a Routing Protocol for Ad Hoc Wireless Networks

1. Mobility

• Problem: Network topology is highly dynamic due to node movement.
• Impact: Frequent path breaks during ongoing sessions.
• Requirement: Routing protocols must efficiently manage mobility.
  • Comparison: Wired network protocols handle path breaks more slowly, making them unsuitable for ad hoc networks.

2. Bandwidth Constraint
